Does "itself" mean something here?

Native speaker’s answer

Reflexive pronouns that end in -self or -selves refer back to and emphasise the subject of the sentence. A synonym could be "by itself" or "alone" or "only". So here, the speaker wants to show that Infarm, and only Infarm, nothing else, saw a huge growth in 2020: Ex: My teacher herself met the President (My teacher *emphasis*, no other teacher, met the president). Ex: LingoTalk itself has welcomed 50% more students in the last month (LingoTalk, and not RedKiwi or any other platform, has welcomed 50% more students).
